`while` Loop:

The while loop executes as long as the specified condition evaluates to true. The condition is evaluated before the code block executes.

Syntax:

while (condition) { 
  // Code to execute 
}

Example

let count = 0;

while (count < 5) {

console.log(count);

count++;

}

Try it yourself

`do...while` Loop:

The do...while loop executes the code block at least once, regardless of the condition. The condition is evaluated after the code block executes.

Syntax:

do {
    // Code to execute
} while (condition);

Example

let count = 0;

do {

console.log(count);

count++;

} while (count < 5);
